An important aspect of robust automated assembly is an accurate and efficient method for the inspection of finished assemblies. This article presents a novel multiscale assembly inspection algorithm that is used to detect errors in an assembled product. The algorithm is trained on synthetic images generated using the CAD model of the different components of(More)
We develop a novel multiscale stochastic image model to describe the appearance of a complex three-dimensional object in a two-dimensional monochrome image. This formal image model is used in conjunction with Bayesian estimation techniques to perform automated inspection. The model is based on a stochastic tree structure in which each node is an important(More)
| Visual assembly inspection can provide a low cost, accurate, and e cient solution to the automated assembly inspection problem, which is a crucial component of any automated assembly manufacturing process. The performance of such an inspection system is heavily dependent on the placement of the camera and light source(s). This article presents new(More)
Surgical treatment remains the only curative treatment for gallbladder cancer. However, even after liver resection, locoregional failure seems to be a significant problem. While there is no Level I evidence, multiple studies have shown benefit for adjuvant radiation in high-risk patients. After extensive liver resection, tolerance to conventional(More)
The continuous improvement of education programs relies on assessment of the learning outcomes of the program as well as associated courses. Proper mapping of various assessments and learning outcomes directly impacts the quality and accuracy of the results. Yet, lack of a concise definitions combined with the large number of assessments and outcomes(More)
